Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The Global Positioning System (Global Positioning System) is a new generation satellite Positioning and navigation System which is developed from the 70 th century in the united states and is fully built in 1994 and has the capability of Positioning in sea, land and air and omnibearing real-time navigation. The GPS system can be used for measurement and navigation, and can also be used for speed measurement and time service. The information such as the driving route, the position, the speed, the altitude and the like of the vehicle can be obtained by accurately positioning the satellite signals received by the GPS.
Therefore, the inventor creatively proposes one of the core concepts of the embodiments of the present invention, that is, in the event of a match, a GPS device is placed on a relay truck, an electronic map image is generated based on the current path information acquired by the GPS device, and the electronic map image is superimposed and output with a video background image captured by a camera as a subtitle image. Thus, the television picture presents more than a single athlete running picture, which can add features to the television content and meet the audience demand for game information volume.
Referring to fig. 1, a flowchart of an embodiment 1 of a rebroadcasting method for a marathon race according to the present invention is shown, which specifically may include:
step 101, acquiring current path information of a marathon match by using GPS equipment, wherein the current path information comprises longitude and latitude information;
in a particular implementation, the GPS device may be placed in a relay truck. Therefore, according to the principle of the global satellite positioning technology, the GPS equipment can receive and analyze orbit information and time information in electric waves returned by a plurality of satellites in space, and calculate longitude and latitude information of the current position, namely position information of the position point of the GPS equipment, as current path information in the marathon competition.
102, calling map information in a map library based on the longitude and latitude information to generate a map image of the current path;
map libraries, i.e., databases that include a large amount of map information. The types of map libraries are many, including map libraries all over the country, Chinese map libraries, and world map libraries. In a specific implementation, a person skilled in the art can select a corresponding database as needed. For example, a map library of the venue of the match is selected, and a mansion map library is used for the mansion international marathon match.
The map image generated in this step will be used as a caption screen, and therefore, the size of the generated map image should have a certain specification, which is set as W × H, where W is the image width and H is the image height.
In a preferred embodiment of the present invention, the step of generating the map image of the above-mentioned size specification may include the following sub-steps:
a substep A1, calling map information in a map library according to the longitude and latitude information to generate a map image with a first preset size;
a substep A2, finding a mapping point in the map image according to the longitude and latitude information;
and a substep a3 of cutting out a map image of a second preset size W × H from the map image with the mapping point as a center point, as a map image of the current route.
The preferred embodiment adopts a mode of generating first and then intercepting, because the current path, that is, the position of the position point where the GPS device is located, in the map image generated in sub-step a1 is relatively random, the map image with the above-mentioned size specification is finally obtained by searching for the mapping point in sub-step a2 and intercepting in sub-step A3.
It can be understood that the map image with the above size specification may also be generated in a manner that the map image with the above size specification is generated at one time by directly using the current path, that is, the location point where the GPS is located, as the center point of the map image. Those skilled in the art can use the above two generation methods as required, and the present invention is not limited thereto.
After obtaining the map image, in order to make the audience better appreciate the game, in a preferred embodiment of the present invention, a manner of displaying the game route on the map image is adopted, and specifically, two schemes may be included:
in a first scheme, an online rendering method may specifically perform the following steps before the step of superimposing and outputting:
and drawing a competition route on the map image according to the acquired path information, and taking the drawn map image as a subtitle picture.
In practice, the route of the marathon race is composed of a plurality of path nodes. Taking the route of 2009 beijing international marathon as an example: turning to the north from the east side of Tianan gate, turning to the west, turning to the north from the right along the Changan gate bridge, turning to the west from the left along the two-ring auxiliary path, turning to the north from the west along the North bridge of Yutan gate to the north along the Right of Sanlihe river crossing.
These path nodes may be divided and labeled, for example, the Tiananmen square as the starting point is the 1 st path node, the reviving gate bridge is the 2 nd path node, the lunar north bridge is the 3 rd path node, and the Olympic track and field is the N +1 th path node.
Then these path nodes may also be highlighted when displaying the race route. As an example, the following steps may be performed before the step of superimposing outputs:
drawing a competition route on the map image according to the acquired path information;
and when a certain path node is passed, marking the path node on the competition route, and drawing and marking a map image as a subtitle picture.
It is to be understood that the indicia may be in the form of numerical numbers, and the invention is not limited in this regard.
In a second scheme, the offline rendering method may specifically perform the following steps before the overlay output step:
when the route is decorated or surveyed, GPS equipment is utilized to collect competition path information;
drawing a competition route according to the path information;
and when the current longitude and latitude information is matched with the longitude and latitude information in the competition route in a field detection manner, calling the route where the matched longitude and latitude information is located from the competition route, and overlapping the route into the map image, wherein the overlapped map image is used as a subtitle picture.
And 103, taking the map image as a subtitle picture, and overlapping and outputting the subtitle picture and a video background picture shot by the camera.
In a rebroadcasting car for marathon competition, besides the GPS device, the rebroadcasting car generally includes a plurality of cameras, a caption machine and a switching station system, and at this time, the caption machine operates in an external key mode, and the switching station system screens a selected video background picture from input signals of the plurality of cameras and superimposes and outputs a caption picture of the caption machine with the video background picture.
In a specific implementation, the subtitle picture may have two presentation forms: a landscape crawl format and a portrait crawl format. Referring to fig. 2, 3, and 4, there are shown an original video screen of a marathon race, a screen in which a horizontal map image is added to the original video screen, and a screen in which a vertical map image is added to the original video screen, respectively. Therefore, the invention enables the television picture to present more than a single athlete running picture, can increase the ornamental value of the competition, and provides good visual enjoyment for audiences, thereby meeting the requirement of the audiences on the competition information amount.
Assuming that the original video picture size is 640 × 480, the size specification of the map image generated in step 102 may be 640 × H corresponding to the landscape crawl format; the size specification of the map image generated in step 102 may be W × 480 corresponding to the vertical scroll subtitle form.
Of course, those skilled in the art can set map images with other dimensions as the subtitle picture according to actual requirements, and the present invention is not limited thereto.
Referring to fig. 5, a flowchart of embodiment 2 of a rebroadcasting method for a marathon race according to the present invention is shown, which specifically includes:
501, acquiring current path information of a marathon match by using GPS equipment, wherein the current path information comprises longitude and latitude information and moving speed information;
step 502, calling map information in a map library based on the longitude and latitude information to generate a map image of the current path;
step 503, making a first subtitle according to the currently acquired moving speed information;
and step 504, taking the map image and the first caption as caption pictures, and overlapping and outputting the caption pictures with a video background picture shot by a camera.
Because the GPS equipment can receive and analyze the orbit information and the time information in the electric waves returned by the satellites in the space and calculate the moving speed of the current position, if the current speed can be displayed on a television picture, not only can the characteristics be added to the television content, but also the competition information amount can be provided for audiences.
Therefore, the present embodiment is different from embodiment 1 in that a first subtitle is produced based on the current moving speed information acquired by the GPS device and is presented to the viewer as a subtitle screen.
Referring to fig. 6, a flowchart of embodiment 3 of a rebroadcasting method for a marathon race according to the present invention is shown, which specifically includes:
601, acquiring current path information of a marathon match by using GPS equipment, wherein the current path information comprises longitude and latitude information and time information;
step 602, calling map information in a map library based on the longitude and latitude information to generate a map image of the current path;
step 603, taking the difference between the currently acquired time information and the time information acquired at the beginning of the competition as competition time information;
step 604, making a second subtitle according to the competition time information;
and step 605, using the map image and the second caption as caption pictures, and overlapping and outputting the caption pictures with the video background pictures shot by the camera.
GPS is not only a high precision global positioning system, but also a high precision real time standard time signal. The time unification can provide unified standard time information and standard time signals for missile, space test and large-scale test systems, so that the time unification of a set of system consisting of various electronic devices and computers is realized.
The difference between this embodiment and embodiment 1 is that the GPS device is used to obtain standard time information, and based on the information, the elapsed time of the current match, that is, match time information is calculated and displayed on the television screen, so that the amount of match information can be provided to the audience.
Referring to fig. 7, a flowchart of an embodiment 4 of a rebroadcasting method for a marathon race according to the present invention is shown, which specifically includes:
step 701, acquiring current path information of a marathon match by using GPS equipment, wherein the current path information comprises longitude and latitude information;
step 702, calling map information in a map library based on the longitude and latitude information to generate a map image of the current path;
703, calculating to obtain competition distance information according to the current longitude and latitude information and the longitude and latitude information of the starting point of the competition;
step 704, making a third subtitle according to the competition distance information;
step 705, the map image and the third caption are used as caption pictures, and are overlapped with the video background picture shot by the camera for output.
The difference between this embodiment and embodiment 1 is that the current path and the starting point of the competition are taken as two points on the spherical surface of the earth, and therefore step 703 is to know the longitude and latitude coordinates of the two points and solve the problem of the spherical distance; and, the spherical distance is used as the competition distance information and is displayed on the television picture in the form of subtitles, so that more competition information can be provided for the audience.
The invention also discloses an embodiment 5 of a rebroadcasting method of the marathon competition, which specifically comprises the following steps:
step S1, acquiring current path information of the marathon match by using GPS equipment, wherein the current path information comprises longitude and latitude information, moving speed information and time information;
step S2, based on the longitude and latitude information, calling map information in a map library to generate a map image of the current path;
step S3, making a first caption according to the currently acquired moving speed information;
step S4, taking the difference between the current acquired time information and the time information acquired from the beginning of the competition as competition time information;
step S5, making a second caption according to the competition time information;
step S6, calculating to obtain match distance information according to the current longitude and latitude information and the longitude and latitude information of the match starting point;
step S7, according to the competition distance information, a third caption is produced;
and step 8, using the map image, the first caption, the second caption and the third caption as caption pictures, and overlapping and outputting the caption pictures with the video background pictures shot by the camera.
In the embodiment, subtitles are simultaneously manufactured according to the moving speed information, the competition time information and the competition distance information and are displayed on a television picture. Referring to fig. 8, a picture for increasing the game speed, time and distance information on the original video picture shown in fig. 2 is shown. Seeing the picture, even if the viewer just turns on the television, the match stage is known, for example, by 15.345/42.195 — 0.3637, the match just passed 1/4.
Referring to fig. 9, a flowchart of embodiment 6 of a method for rebroadcasting a marathon race according to the present invention is shown, which may specifically include:
step 901, acquiring current path information of a marathon competition by using a GPS device, wherein the current path information comprises longitude and latitude information, and a route of the marathon competition comprises a plurality of path nodes;
step 902, calling map information in a map library based on the longitude and latitude information to generate a map image of the current path;
step 903, collecting longitude and latitude information of each path node by using GPS equipment;
step 904, obtaining regional characteristic information of each path node;
step 905, aiming at each path node, manufacturing a fourth subtitle according to corresponding characteristic information;
step 906, storing the fourth subtitles of all the path nodes together with corresponding longitude and latitude information to an information file;
the marathon is long in distance and rarely broadcasts marathon events by television stations over time, so that it is a great challenge for commentators to explain marathon events. Many commentators lack commentary due to lack of knowledge about the marathon game, causing dissatisfaction to the audience.
In view of the above situation, the idea of the present embodiment is that since the route of the marathon competition includes a plurality of path nodes, when the competition passes through a certain path node, if the characteristic information of the path node can be broadcast on the screen, the commentary content will be added to the commentator.
Specifically, when a circuit is subjected to color arraying or line surveying in advance, longitude and latitude information of some path nodes in a marathon route is acquired, meanwhile, a subtitle containing characteristic information of each path node is manufactured, and the subtitle and the longitude and latitude information are stored in an information file, so that the subtitle and the longitude and latitude information of each path node are in one-to-one correspondence;
therefore, whether the path node is reached can be judged by detecting whether the longitude and latitude information of the current path is matched with the longitude and latitude information of a certain path node in the information file, so that whether the feature information caption of the path node is broadcasted or not is determined.
Step 907, detecting whether the current longitude and latitude information is matched with the longitude and latitude information of a certain path node in the information file, if so, executing step 908, otherwise, executing step 909;
step 908, using the map image and the fourth caption as caption pictures, and overlapping and outputting the caption pictures with the video background pictures shot by the camera;
and a step 909 of using the map image as a caption image, and overlapping and outputting the caption image with a video background image shot by the camera.
Referring to fig. 10, a picture with path node subtitles added to the original video picture shown in fig. 2 is shown, wherein the science park of the middle guan village belongs to the science region, and the picture adopts a scrolling mode. It is understood that the path node may be a tourist attraction, a business area, etc. besides the scientific area, and the present invention is not limited thereto.
Of course, when a match is detected, a person skilled in the art may also determine whether to play out the caption of the path node according to actual needs, which is not limited by the present invention.
The embodiments in the present specification are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The invention can be applied to the rebroadcasting of the marathon competition, is used for improving the information content of the rebroadcasting and increasing the ornamental value of the competition, further meets the requirement of audiences on the information content of the marathon competition, and can increase the comment content for commentators.
